Please note that the Java Applet's may not run with IE, Please use Netscape Navigator...............
 

If you're into electronic gadgets etc, then you've come to the right place. As I mentioned earlier, I carry out repairs on TV's V.C.R.'s, computers and anything electrical. If you think that I might be able to help you in any way then you are most welcome to e-mail me anytime.
Here is a site that I would recommend to people who carry out there own repairs etc. This site allows you to submit a faulty electronic equipment (Model and Make req'd), and also to view other submissions. If someone has come across a similar fault then they might help you (if you are polite), I found this site very useful.

If you'd like to learn the basic of electronics, then here are some tutorials.

Basic CMOS technology

In CMOS (Complementary Metal-Oxide Semiconductor) technology, both N-type and P-type transistors are used to realize logic functions. Today, CMOS technology is the dominant semiconductor technology for microprocessors, memories and application specific integrated circuits (ASICs). The main advantage of CMOS over NMOS and bipolar technology is the much smaller power dissipation. Unlike NMOS or bipolar circuits, a CMOS circuit has almost no static power dissipation. Power is only dissipated, in case the circuit actually switches. This allows to integrate many more CMOS gates on an IC than in NMOS or bipolar technology, resulting in much better performance.

The following applets demonstrate the N-type and P-type transistors used in CMOS technology, the basic CMOS inverter, NAND and NOR gates, and finally a AOI32 complex gate.

The first applet illustrates the function of both N-type and P-type MOS transistors.

Click on the source and gate contacts of the transistors to toggle the corresponding voltage levels and watch the resulting output value on the drain contacts. The applet uses colors to display the different voltages.

Note that the N-type transistor is conducting when its input is '1', while the P-type transistor is conducting when its input is '0'. The applet displays the channel of a conducting transistor as a rectangle filled with the color of its source voltage. The channel of a nonconducting transistor is shown as rectangle outline in black.
